Those are the big things. Might sound silly, but I also want to keep the 430 cosmetically nice. A daily driver is going to take a beating with weather, door dings, etc. In essence, it's a luxury item.
The other things are undue attention, little usable space, and impracticalbility. For examples, I would feel uncomfortable for clients to know I have a Ferrari and I can't pick up my kids in the car (two seater).
Like I said, I love the M3 as a practical sports car. Fun to drive and able to do a lot of functions well. Even when I had a GT3, I found it hard to drive everyday. Great track car, but a crappy daily driver.
